CAMSHAFT JOURNAL I.D.
Install each journal onto the cylinder head and tighten
them to the specified torque.
Measure the I.D. of each camshaft journal.
STANDARD:
29.000 – 29.024 mm (1.1417 – 1.1427 in)
CAMSHAFT OIL CLEARANCE
Clean off any oil from the camshafts, camshaft holders
and rocker shaft holders. Check each journal for
excessive wear or damage.
Install the rocker shaft holders, camshafts and camshaft
holders and tighten the bolts to the specified torque
(page 14-31).
Remove the camshaft holder and camshaft, then set a
plastigauge (1) on each journal as shown.
• Set the plastigauge in the axial direction on each
journal.
• Position the plastigauge away from the oil passage.
Reinstall the camshaft holders and tighten the bolts to
the specified torque (page 14-31).
• Do not turn the camshaft during inspection.
Remove the camshaft holder and measure the width of
the pressed part of the plastigauge using a scale (2)
printed on the bag of the plastigauge.
STANDARD:
No.1: 0.030 – 0.069 mm (0.0012 – 0.0027 in)
No.2 - 0.060 – 0.099 mm (0.0024 – 0.0039 in)

SERVICE LIMIT:
No.1: 0.15 mm (0.006 in)
No.2 - 0.15 mm (0.006 in)

If the measurement still exceeds the service limit,
replace the camshaft (page 14-26).
